MANIFOLDING- DEVICE.

Specication of Letters Patent.

Patented Mar. 2a, 1914.

Application led August 9, 1912. Serial No. 714,231.

To all whom t may concern Be it known that I, WALTER J. GRAY, Jr., a citizen of the United States, residing at Hamilton, Ohio, have invented a new and useful Improvement in h'lanifolding. Devices, of which the following is a specification.

My invention relates to lnanifolding devices adapted to the use of autograplnc registers or for other suitable purposes, and the objects of my improvement are to provide a holder for the carbon paper which may be used as an attachment to the ordinary regis- A ters; to provide convenient means for shifting the carbon paper as desired; to provide means for maintaining the carbon paper under the proper tension; and to provide simple and durable construction andassemblage of the various parts for securing' facility of operat-ion and etliciency ofaetion. These objects may be attained in the following described manner as .illustrated in the accompanying drawings, 1n which z:

Figure 1 is a plan with parts broken away 0I an autographic register provided with my device; Fig. 2,`a transverse section on the line a-a of Fig. 1; Fig. 3 a plan of por-A .tions of the carbon roller, and Fig. el a transversesection thereof; Fig. 5 an end elevation of the ratchet wheel, and Fig. 6 a section of parts on the line a-a of Fig. 1 in an opposite direction from that of Fig. 2, showing the position of the pawl and ratchet wheel within a recess of the casing.

In the drawings, 1 and 2 represent a portion of the side walls of an autographic register, 3 the platen, 4 and 5 the paper rollers,-

and 6 the cover, all being constructed and arranged in the ordinary manner.

A roller 7 journaled in a bracket 8 may be ,removably secured on wall 1 directly opposite the edge of the platen by means of screws 9. A casing 11 wherein a similar roller 12 is journaled may be removably secured in a similar position on wall 2 by means of screws 13. Said casing is formed with a semi-circular bottom 14: for supporting therein the roll 15 of carbon paper and with an interior recess 16 in its front end wall 17. The roller 18 is formed with an enlarged journal 19 adjacent to its head 21 whereby it may be journaled within the enlarged opening or bearing 22 formed in the rear end wall 23 of the casing and which also permits said roller to be removably inserted therethrough. A ratchet wheel 24 formedwith an angular opening 25, as shown in Fig. 5, may be removably secured on the corresponding angular portion 26 of the roller 18 to cooperate with the pawl 27 mounted within the recess 16. Said ratchet wheel is formed with a series of openings 2S through its wall for the removable insertion therein of the end cf the clamping bar 20 which is secured at its opposite end within an opening 2O formed in the end'of the journal 19 contiguous to the surface of the roller 18, as shown in Fig. 4. A thumb nut 31 may be removably secured on the threaded end portion 32 of the roller 1S for maintaining it in proper position within the casing and also for turning it when desired. A suitable removable cover (not shown) may be provided for the casing 11 for excluding the dust and protecting its contents.

In operation, a roll 15 of double faced carbon p-apcr 30 may be supported within the casing upon the semi-circular rbottom and partially unrolled with its end portion extended over roller 12 and transversely across the platen between the sheets 33 and 34 of record paper placed thereon. Said end portion may then be extended under roller 7 and returned thereover and across the platen between the sheets 34 and 35 of record p-aper and again over the roller 12 and terminate inclamping engagement with roller 1S. The nut on roller 18 may be removed or loosened suiiiciently for said roller to be moved longitudinally in its bearings for disengaging the end of the clamping bar from the ratchet wheel for inserting the end of the carbon paper thereunder when the end of the bar may be rengaged with the ratchet wheel and maintained in `clamping engagement by means of the nut. By turning the roller 18 in the direction of the arrow the worn portion Vof the carbon paper in registration with the platen may be wound thereon and succeeded by a fresh portion being simultaneously unwonnd from the roll 15 into proper position over the platen. The pawl and ratchet wheel serves to prevent any reverse movement of the roller 18 and maintains the carbon paper at the proper tension. A plural number of sheets of carbon may be rolled together in forming the roll 15 and actuated simultaneously by roller 18 and in the same manner as a single sheet, for manifolding an increased number of record sheets. The matter written on the top sheet of record paper over usual manner.

the platen may thus be copied on each of the sheets thereunder when they may be advanced with the bottom sheet extended under the cover and the others torn off in the The location of the nut is most conveniently accessible to the operator for facilitating the shifting of the carbon paper.

Having fully described my improvement, What I claim as my invention and desire to secure by Letters Patent of the United States is 1. A manifolding device comprising av frame, a platen thereon for supporting superposed 'strips of record paper, a casing secured on one side of the frame and formed with a curved bottom, guides supported respectively on the casing and on the opposite side of the frame adjacent to the platen, an actuating roller journaled in the casing, a strip of carbon paper formed'into a roll and supported on the bottom of the casing, said strip of carbon paper being directed by the guides transversely across and back again over the platen and between corresponding strip of carbon paper may be Wound at in tervals from the roll as desired.

2. In a manifolding device the combination with a frame, a platen thereon for supporting superposed strips of record paper, and a guide on one side of the frame, of a casing removably secured 011 the other side thereof and formed With a curved bottom, said casing being provided With a corresponding guide and with a removable roller, and a stripof carbon paper formed into a roll and supported Within the curved bottom of the casing, said strip being directed by the guides transversely across and back again over the platen and between corresponding strips of record paper thereon, and terminating in detachable engagement with the removable roller, for the purpose speci- 45 fied.
